4 Claims. (tCl. 292-173) This invention relates in general to certainnew and useful improvements in door locks and, more particularly, to alock adapted for use on vehicular body doors, such as truck doors andthe like.

It is the primary object of the present invention to provide a door lockof the type stated which is simple and economical in construction andwhich can be readily installed on all types of sheet metal doors with aminimum or labor cost.

It is another object of the present invention to provide a door lock ofthe type stated which is relatively waterproof.

It is a further object of the present invention to provide a door lockof the type stated which is easy to manipulate and is relativelyshockproof and rattleproof.

With the above and other objects in view, our invention resides in thenovel features of form, construction, arrangement, and combination ofparts presently described and pointed out in the claims.

In the drawings-- Figures 1 and 2 are fragmentary front and rearelevational views, respectively, of a door having a door lockconstructed in accordance with andembodying the present invention;

Figure 3 is a fragmentary vertical sectional View taken along line 3-3of Figure 1;

Figure 4 is a fragmentary sectional view similar to Figure 3, showingthe door and lock structure in unlocked and outwardly swung position;and

Figure 5 is a fragmentary sectional view taken along line 5-5 of Figure3.

Referring now in more detail and by reference characters to thedrawings, which illustrate a preferred embodiment of the presentinvention, ll designates a conventional door hingedly mounted forclosure-Wise disposition against a jamb 2. Preferably, though notnecessarily, the door 1 and jamb 2 are fabricated of sheet metal andhave not been illustrated in detail inasmuch as these elements may be ofany conventional design and do not specifically constitute the presentinvention. For present purposes, it is merely sufiicient to point outthat the door 1 is provided with a suitably flanged rectangular aperture3 for receiving the door lock A, which comprises a stamped rectangularcup 4 having a continuous flat peripheral flange 5. is of such size andshape as to accommodate the cup 4 and the flange 5 is tightly secured tothe door 1 by means of rivets 6. The cup 4 is provided with a flat backWall 7 having an oblong or somewhat elliptical central slot 8, themargins of which are struck up in the formation of an outwardly raisedrim 9.

Spot-welded or otherwise rigidly secured to the rear face of the backwall '7 is a U-shaped channel It integrally including outwardly turnedattachment flanges 11, 11, legs l2, l2, and a flat bight 13. The channelIt) is centered with respect to the vertical center line of the slot 8and has open ends respectively above and below the slot it to provide aslide for accommodating a vertically It is, of course, obvious that theaperture 3 ates Patent shiftable bolt 14, which is preferably formedfrom sheet metal and integrally includes a central section 15, sideflanges 16, 16, and an angularly bent top section or striker-face 17.The central section 15 is provided with an elongated central slot 18aligned with the slot 8 and an inwardly struck ear 19, which istack-welded at its rear margins to the flanges 16, 16', in order to lendrigidity and strength to the structure.

Rigidly mounted in, and projecting inwardly from, the opposite sideWalls of the cup 4 are axially aligned hinge pins 20 for rockablysupporting a handle 21, which inte grally includes an arcuategrip-section 22 and lateral flanges 23. Welded or otherwise rigidlysecured to the inner face of the grip-section 22 is a U-shaped actuatorlink 24 integrally including legs 25, 25, and a fiat relatively widebight 26 extending across the slot 8 and being provided on its inwardlypresented face with a rubber gasket 27 adapted for sealing engagementwith the rim 9 when the door look A is in closed or locked position.Rigidly mounted in the bight 26 is an actuator pin 28 which projectsrearwardly through the slots 3, 18, for operative engagement against thelower margin of the slot 18 and the car 19.

Secured upon the back face of the bight 13 of the channel 10 by means ofa screw 29 is a plate 30 having an inwardly bent tongue 31 located inunderlying relation to the car 19 and interposed between the tongue 31and ear 19 is a compression spring 32 for normally biasing the bolt 14upwardly to the position shown in Figure 3. Shiftably mounted in theupper end of the bight 13 of the channel Ill and the plate 30 is apressure pin 33 having a rounded head 34 bearing slidably against theinner face of the bolt 14 and biased by a compression spring 35 disposedencirclingly thereabout.

When the door lock A is properly mounted in the door 1, the bolt 14 willengage the jamb 2, as shown in Figure 3, and will hold the door 1securely in place. The spring 35 and pressure pin 33 will introduce alimited degree of resiliency which will compensate for wear andvibratory stresses, so that the door 1 will always remain tight. Inorder to release the door lock A and open the door 1, the grip-section22 of the handle 21 is manually swung upwardly, causing the actuator pinto swing downwardly and thereby shifting the bolt 14 downwardly againstthe bias of the spring 32 until the upper end of the bolt 14 is fullyretracted and the door 1 is free to swing open. As soon as thegrip-section 22 of the handle 21 is released, the bolt 14 returns toinitial position, so that the door 1 may again become looked as it isreturned to closed position. i

It should be understood that changes and modifications in the form,construction, arrangement, and combination of the several parts of thedoor lock may be made and substituted for those herein shown anddescribed without departing from the nature and principle of ourinvention.

Having thus described our invention, what we claim anddesire to secureby Letters Patent is:

1. A door lock comprising a cup-like element adapted to fit into andextend through a door with its open end presented outwardly with respectto one face of the door, said cup-like element having a back wallapproximately aligned with the other face of the door and being providedwith an aperture, a slide-forming element rigidly secured upon the backwall in overlying relation to the aperture and projecting inwardly fromsaid other face of the door, a bolt shiftably mounted in theslide-forming element and having an abutment located across saidaperture, a pivot pin disposed in outwardly spaced relation to the boltwith its longitudinal axis perpendicular to the path of movement of thebolt and in a plane parallel thereto, a handle rockably mounted in thecup-like element for rotation about the pivot pin, said handle having aflat hand-grip portion disposed in radially offset relation to the pivotpin, a flat member attached to the hand-grip portion in radiallyoutwardly spaced relation to the pivot pin and in inwardly spacedrelation to the hand-grip portion, said flat member being provided, uponits inwardly presented face, with a gasket of such size and relativeposition as to extend sealingly across the aperture when the bolt is inlocked position, and an actuating element operatively connected to theflat member and projecting through the gasket and aperture forengagement against the abutment on the bolt, whereby the bolt isretracted into the slide-forming element responsive to rocking move mentof the handle, said actuating element being so located that the bolt,when in locked position, tightly engages the actuating element andthereby applies inward force to the flat member to hold the gasket inseal-forming position across the aperture.
